| Identity & Market | ||
| Base polymer / chemistry | Polyether ketone ketone, amorphous grade — a polyaryletherketone that stays amorphous, so it does not need PEEK's crystallisation control. Stratasys sells it as Antero 800NA and Antero 840CN03; category numbers below are unfilled unless a carbon grade is named[1][2] | PLA compounded with a mineral filler — Fiberlogy names chalk — that scatters light into a diffuse finish[3][4] |
| Densityg/cm³ | 1.28 unfilled (ASTM D792, Antero 800NA; 1.31 annealed) and 1.33 for CarbonX PEKK-A CF15 (ISO 1183)[2][1] | 1.31 (Bambu Lab, ISO 1183) to 1.38 (Fiberlogy PLA Mineral, method not stated) — above plain PLA from the filler[4][3] |
| Typical priceUSD/kg | 1 kg-equivalent spools cluster near 550[5][6][7] | Mainstream 1 kg spools cluster near 21[8][9][10] |
| Price range across brandsUSD/kg | 333-771 across grades and formats; 3DXTech CarbonX PEKK-A+CF15 333 at 2 kg, 3D4Makers unfilled PEKK-A 485 at 2 kg, IEMAI 3D 500 at 1 kg, Kimya PEKK Carbon 771 at 500 g[5][6][7][11][12] | 11–32 across brands; budget house brands 11–19, Fiberlogy PLA Mineral 32[13][9][14] |
| Market availability1–5 | Niche, a handful of specialist brands[5][6][7] | Stocked by most mainstream brands[13][10][8] |
| Spool sizes & diameters | 1.75 and 2.85 mm; 200 g to 2 kg spools, plus Stratasys canisters[5][6][2] | 1.75 mm; 1 kg spools plus spool-less refills[8][15] |
| Typical applications | Aerospace interior and structural parts; 3DXTech labels its carbon-filled PEKK-A grade AERO and Stratasys certifies Antero 800NA for outgassing and FST[1][2] | Display models and visible parts where a matte, non-reflective finish matters[4] |
| Diameter tolerance± mm | Not documented | ±0.03 (Bambu Lab)[16] |
| Printing Parameters | ||
| Nozzle temperature°C | Not documented | 190–230 (Bambu Lab); 190–210 (Fiberlogy PLA Mineral)[4][3] |
| Bed temperature°C | 140 (3DXTech CarbonX PEKK-A CF15)[1] | 35–45 (Bambu Lab); 60 (Fiberlogy)[4][3] |
| Enclosure / chamber requirement1–5 | Actively heated chamber required[17][18] | Open frame is fine[4][3] |
| Part cooling fan | Not documented | Fan on; Fiberlogy specifies 75–100 %[4][3] |
| Bed surface & adhesion aid | Not documented | Cool plate, high-temperature plate or textured PEI with glue (Bambu Lab); smooth PEI, textured PEI or glass (Fiberlogy)[4][3] |
| Warping tendency1–5 | Not documented | None[4] |
| Bed-adhesion difficulty1–5 | Not documented | Sticks to anything[19] |
| Overall printing difficulty1–5 | Expert / industrial hardware only[17][18] | Beginner — prints on any machine out of the box[4][3] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Hardened steel required — the category spans unfilled PEKK, where brass is acceptable, and the carbon-filled aerospace grades that make up most of the market[1][2] | Brass fine indefinitely[20][4][3] |
| Abrasiveness1–5 | Highly abrasive — most PEKK filament sold is carbon-filled; unfilled Antero 800NA and ThermaX PEKK-A are non-abrasive[1][2] | Slightly abrasive — mineral filler pushes density from 1.24 to 1.31–1.38[3][4][21] |
| Nozzle clog risk1–5 | Moderate — needs dry filament and a clean nozzle; 3DXTech lists no special nozzle concerns but a mandatory 120 °C pre-dry before every print[22] | Very low[20] |
| Heat-creep / jam sensitivity1–5 | Not documented | Moderate — good heatbreak cooling needed; PLA softens below 60 °C[23] |
| Hotend requirement | Not documented | No special hot-end required[19] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Not documented | Moderate — 0.40 % saturated at 25 °C / 55 % RH[4] |
| Equilibrium moisture content at ~50 % RH% | Not documented | 0.40 saturated at 25 °C / 55 % RH (Bambu Lab)[4] |
| Drying temperature & time | Not documented | 50 °C for 8 h in a forced-air dryer, or 60–70 °C for 12 h on an X1 heatbed; Fiberlogy specifies 50 °C for 6 h[4][3][24] |
| Symptoms when wet | Not documented | Bubbling and popping at the nozzle, stringing, rough surface and weak layers[25] |
| Effect of moisture on strength | No dry-versus-conditioned figures are published; 3DXTech mandates a 120 °C, 4 h pre-dry before every print because trapped water flashes to steam at these nozzle temperatures[22] | Polymaker rates PLA low-sensitivity — the loss shows as poor layer adhesion and brittle layers rather than a published strength figure[25] |
| Storage requirement | Not documented | Sealed with desiccant below 20 % RH; shelf life at ambient is long[21][19] |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 86.7-90.0 at yield and 73.0 at break (printed XZ, ASTM D638, Antero 800NA on the F900 and Fortus 450mc); 88.8 at break annealed; 126 at break for CarbonX PEKK-A CF15 (printed XY, ISO 527)[2][1] | 30 (printed XY, ISO 527, Bambu Lab); 35.1 on My Tech Fun bars for PolyTerra PLA[4][26] |

| Other impact data | Izod notched 41.1 J/m XZ and 33.3 J/m ZX; unnotched 1730 J/m XZ against 203 J/m ZX (printed, ASTM D256/D4812, Antero 800NA)[2] | Izod 6.1 kJ/m² on My Tech Fun printed bars for PolyTerra PLA[26] |
| Layer adhesion / Z tensileMPa | 50.1-59.4 at yield (printed ZX, ASTM D638, Antero 800NA); 56.0 for the ESD grade Antero 840CN03[2][27] | 22 (printed Z, ISO 527); flexural Z falls to 29 against 53 in XY; 12.9 on My Tech Fun layer-adhesion bars[4][26] |
| Brittleness1–5 | Moderate unfilled — 6.1 % elongation at break in plane; brittle in the carbon-filled grades at 3.15 %[2][1] | Brittle — snaps with little warning[4] |
| Creep resistance / sustained load1–5 | Excellent — holds load for years. Antero 800NA still holds 82 % of its room-temperature ZX tensile strength at 104 °C and 63 % at 132 °C (printed, ASTM D638)[2] | Poor — 12 mm bar sagged to 18.7 mm over 5 days at 1.25 kg[26] |
| Fatigue / repeated-flex resistance1–5 | Not documented | Poor — no grade-specific S-N curve; plain printed PLA ran 38 000–49 000 cycles at 30 % of tensile strength (R = 0.2)[28][23] |
| Elasticity / flexibility1–5 | Rigid[1] | Rigid[4] |
| Z strength as % of XY% | 56-82 (Antero 800NA and 840CN03 printed on the F900 and Fortus 450mc, ZX against XZ tensile yield and break, ASTM D638)[2][27] | 73 by tensile, 55 by flexural (printed, Bambu Lab)[4] |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | 158 (printed XY and ZX, ASTM D648 Method B at 66 psi, Antero 800NA); 285 for CarbonX PEKK-A CF15 (ISO 75 at 0.45 MPa)[2][1] | 58 (Bambu Lab) and 48 (Fiberlogy PLA Mineral), ISO 75 at 0.45 MPa[4][3] |
| HDT at 1.8 MPa°C | 156-157 (printed, ASTM D648 Method B at 264 psi, Antero 800NA); moulded 147[2] | 52 (ISO 75, 1.8 MPa)[4] |
| Glass transition (Tg)°C | 156 (ASTM D7426, Antero 800NA); 165 for CarbonX PEKK-A CF15 (DSC)[2][1] | 61 (DSC)[4] |
| Melting point / Vicat°C | 300 melt point (ASTM D7426 peak heat, Antero 800NA); 305 for CarbonX PEKK-A CF15 (DSC)[2][1] | 163 peak melt (DSC); Vicat 63 °C[4] |
| Continuous service temperature°C | Not documented | 54 — loaded bars begin to move at this temperature[26] |
| Annealing response | Not documented | 50–60 °C for 6–12 h; some prints deform or warp, and a forced-air oven is required[4] |
| Thermal expansion (CTE)µm/m·K | 36.1 in XY and 50.2 in ZX (printed, 40-140 °C, ASTM E831, Antero 800NA); 47.4 and 51.2 for the ESD grade Antero 840CN03[2][27] | Not documented |
| Flammability / UL 94 | Not documented | Flammable; no UL 94 rating published by the major brands[21][29] |
| Environment & Chemical | ||
| UV resistance1–5 | Good — years with some colour shift. 1000 h of QUV cycling to ASTM G154 left Antero 800NA's yield strength unchanged at 57 MPa and raised stress at break 3.6 %[2] | Degrades within weeks outdoors[23][30] |
| Chemical resistance | Not documented | Good against weak acids, oils and grease; poor against strong acids and alkalis; dissolved by chloroform, THF and hot benzene[29][23] |
| Water / humidity resistance in service1–5 | Not documented | Good — insoluble in water[21] |
| Food contact | Not documented | Base resin is food-contact grade, but printed layer grooves harbour bacteria; Prusa advises against food use[23] |
| Biodegradability / compostability | Not documented | Industrially compostable only — needs sustained 55 °C; not home compostable[31][23] |
| Recyclability | Not documented | Mechanically recyclable; not accepted in household plastic collection[31] |
| Electrical & ESD properties | Unfilled PEKK is an insulator at above 1.4e14 ohm-cm (ASTM D257); CarbonX PEKK-A CF15 sits above 10^7 ohm/sq, and the Antero 840CN03 ESD grade is specified at 10^4-10^9 ohm-cm[2][1][27] | Not documented |
| Health & Safety | ||
| Fume toxicity1–5 | Moderate — measurable VOCs and UFPs, ventilation advised. None of these polymers was in the chamber study, and all are processed far above the temperatures it covered[32] | Low hazard — minimal VOC and particle emission[32] |
| Ventilation / filtration requirement1–5 | Ventilated room or enclosure recommended[32] | None needed in a normal room[32] |
| Dust & fibre handling hazard | Carbon fibre is bound in the matrix; sanding dust should not be inhaled[1] | Not documented |
| Post-Processing | ||
| Sanding & machining | Not documented | Wet sanding — dry sanding heats the surface by friction and smears it[30][23] |
| Gluing & solvent welding | Not documented | Cyanoacrylate for most joints; some grades partially dissolve and bond with acetone[23][33] |
| Vapour / chemical smoothing | Not documented | No practical vapour smoothing — only chloroform, hot benzene or THF, which are laboratory-only[23] |
| Support material pairing | Not documented | Support for PLA (Bambu Lab)[4] |
| Dimensional accuracy & detail | Not documented | Matte surface hides layer lines; 55° overhangs and 30 mm bridges as for plain PLA[4] |
| Solvents & Solubility | ||
| Soluble in | Concentrated sulphuric acid, as for PEEK; no common organic solvent touches a polyaryletherketone.[34][35] | Chloroform: 10 % w/v in 2–4 h at 23 °C, every grade and morphology; THF and DMF only at 65 °C. Laboratory reagents.[36] |
| Softened or crazed by | Concentrated sulphuric acid and liquid Freon are the entries Ensinger marks not resistant; acetone, MEK and toluene do nothing.[34] | Acetone, ethyl acetate and toluene plasticise it but dissolve <1 % even at 65 °C; submersion in acetone crazes and destroys parts.[36][37] |
| Solvent welding & smoothing agent | None — no solvent softens a polyaryletherketone.[34] | Chloroform vapour smooths and welds PLA at the cost of tensile strength; acetone does not smooth it at all.[38][37] |
